This ebay Buy-It-Now offering provides a new Snap on MG725 or PT850 1/2" drive hammer frame kit. These items do not come with any factory sealed packaging as shown above. This unit is intended for use on Snap on MG725 and PT850 models as sold and shipped. Note to all buyers in need of hammer frames and pins for this MG725 Snap on tool. While a hammer frame and pins can be wearing and maintenance parts it is not necessary to ever need to replace these parts. Hammer frames and pins break because the tool is being pushed too hard for the design features that were engineered into it. Frozen or rusted bolts need the pre-application of penetrating oil, sometimes the employment of a breaker bar and pre-operation chasing of the available exposed fastener threads can help. In the extreme a 3/4" drive impact wrench which is designed for higher tensile strength loading is the best option. I recognize that this is not practical nor desirable for most flat rate mechanics but it is still worth a mention. Replacing broken hammer frames and pins should include a new set of vanes and servicing the air motor to keep the tool operating at maximum effectiveness. Ignoring rotor vane wear or condition can mean: longer hammering times, hotter internal tool parts and then destruction and breakdown. Use a 30 weight non-detergent oil for best recommended OEM requirements. I use synthetic gear oil and ATF which is not OEM recommended. 4 tablespoons or filling the front end plate cavity prior to tool assembly is how it is best accomplished.
